Relcrrin to the drawings:

Figure l is a side elevational view of a hook constructed in accordancewith the present invention.

' Figure F2 is an elovational riew oi the hook; disclosing: one oi theside edges the root.

Figure is a sectional view taken on line 3-3 oi" Figure 2.

Referring; to the drzuviug in (l xail. the hook embodies a body portion5 formed with opposed arms 6 and T respectively, the are! t3 lJQlIlgfcut away as at d to accommodate one end. oil, the pivoted latch member5). This hitch member 9 is secured within the cut away portion 9 bylHMlHS oi? the pivot pin 1.0:, whereby the latch member may swunglaterally, allowing the bail oi a section of well. tubing to passbetween the arms, to so cure the hook.

The arm 7 is also i'ormed with a cut out portion indicated at 11providing a clearance for the free end or": the latch member 9 asclearly shown by Figure 3 of the drawing. The cut out portion 11 isrelatively long as compared with the cut away portion to accommodate thelocking arm 12 which has pivotal connection with the arm 7, as at ill.the arm 12 operating between the walls oil the groove 14- formed alongthe outer surface oi the arm 7.

In order that the locking arm 12 will be normally held in a position tolock the latch member 9 against movement, a spring member 15 isprovided, which spring member has one end thereof secured to the bodyportion 5 as at 16, the opposite end thereof enmur ing the outer surfaceof the arm 12. .i'ls shown, the intermediate portion of the springmember15 normally lies in spaced re lation. with one wall oi? the arm 7 sothat the spring" member may be forced downwznrdly at this point, causingthe locking arm 12 to pivot upwardly. It is to be understood. howeverthat the outer or free end of the member 15 has connection with thearn'i 12 as by means oi"? the pins 17.

Having thus descriliied the invention, what is claimed as new is in abook, a body portion. including opposed arms a latch member supported byone o i' the arms. the opposite arm having an opening to accommodate thetree end or the latch member a locking arm adapted to normally lie inthe path oi travel oi the l atch in out be]? to restrict movementthereof. a spring member having. one end secured to the lockingarm andhaving its opposite end secured to the body portion. the intermediateportion or the spring lying in spaced relation with the body portion topermit the intermediate portion of the spring to move downwardly. androck the locking arm upwardly and release the latch member.

In testimony that I claim the foregoing as my own, I have heretoaii'ixed my signature in the presence of two witnesses.
